THE INTERFERENCE-REJECTED BLIND ARRAY PROCESSING FOR CDMA INTERFERENCE CANCELLATION IN THE NEAR-FAR SITUATION

摘要

A CDMA system is an interference-sensitive system where unequal-power received signals can cause a severe multiple access interference to the system. This problem can be solved by using an antenna array receiver. In this paper, we exploit the concept of the blind array processing for interference canceling receivers along with the parallel interference cancellation for devising the novel structure, namely "An Interference-Rejected Blind Array Processing" which outperforms the original one especially in the Near-Far effect situation. The computer simulation results show that the proposed scheme is better than the original scheme both in the ordering and non-ordering user-power situations.
